Consider a computer program that

  1. accepts 3 numbers as input,
  2. treats each of these numbers as representing the length of the side of a triangle, and
  3. responds with "Is a triangle" or "Is not a triangle" as output.[1]

Generate a comprehensive set of test cases.

Compare your list of test cases to this list of test cases.

Is your list of test cases complete? Are you missing any valid test cases?

Is your list of text cases efficient? Are there any redundant or unnecessary test cases?
